Therefore, further investigation and studies are required to establish the true efficacy of zinc in combating the common cold. In conclusion, maintaining adequate levels of zinc in our bodies is essential for optimal immune function. While some evidence suggests that zinc lozenges may have a modest impact on reducing the duration of a cold, more research is needed to definitively determine the effectiveness of zinc in alleviating the symptoms of this common ailment. Interestingly, some studies have suggested that taking zinc lozenges at the early stages of a common cold may have a slight positive effect on reducing its duration. It is believed that consuming zinc in this form could potentially shorten the length of a cold by approximately two days. However, it is important to note that the severity of the cold symptoms may not be significantly impacted by zinc consumption.

The mineral plays a crucial role in maintaining a healthy skin barrier by aiding in the reduction of inflammation and promoting the regeneration of new skin cells at the site of wounds. This essential function helps protect and strengthen the skin’s natural defense system, ensuring its overall well-being. Additionally, the mineral’s involvement in these processes contributes to the faster healing and improved appearance of wounds, further emphasizing its importance in maintaining optimal skin health.

The recommended intake of zinc.

The amount of zinc required varies depending on an individual’s gender, age, and specific stage of life. To provide comprehensive guidance, recommended dietary allowances (RDAs) have been established for zinc intake according to different age groups.

• Men aged 14 and older: 11 mg
• Women aged 14-18: 9 mg
• Pregnant women aged 14-18: 12 mg
• Breastfeeding women aged 14-18: 13 mg
• Women aged 19 and older: 8 mg
• Pregnant women aged 19 and older: 11 mg
• Breastfeeding women aged 19 and older: 12 mg

The consequences of not obtaining sufficient zinc.

Due to the widespread presence of zinc in the typical American diet, the occurrence of zinc deficiencies in the United States is relatively rare.

When there is a lack of zinc in the body, it can result in a weakened immune system and hindered growth and development in children.

It is worth noting that a lack of zinc in the body can have a dual effect when it comes to diarrhea. On one hand, insufficient levels of zinc can heighten the vulnerability of children to contract diarrheal diseases. On the other hand, the persistence of diarrhea over an extended period can lead to an increased depletion of zinc from the body.

Additional indications and manifestations of inadequate zinc levels encompass diminished desire for food and hindered development in youngsters. In mature individuals, insufficiency of zinc can impede cognitive capabilities and hinder the process of effective wound recovery. Furthermore, the scarcity of zinc may result in the deterioration or modification of sensory perceptions, such as taste or smell.

It is crucial to acknowledge that the symptoms mentioned earlier can arise due to various factors, not exclusively due to zinc deficiency. Therefore, if you suspect that you might be experiencing a zinc deficiency, it is highly recommended to consult your healthcare provider and request them to conduct blood tests in order to evaluate your zinc levels accurately.

Though low zinc levels are fairly rare, individuals at higher risk of zinc deficiency include:⁶

• People living in lower-income countries
• Pregnant women
• Infants, children, and teenagers
• People who are malnourished
• People experiencing chronic diarrhea
• Individuals diagnosed with conditions that can interfere with nutrient absorption, such as celiac disease and inflammatory bowel disease (IBS)
• People who struggle with alcohol abuse
• Vegetarians with limited diets

Quick Recap

Zinc is a crucial mineral that is not naturally synthesized by your body.
